To all whom it concern.-

Be it known that we, TJEBBE D. BEINTEMA and D101: DE R001, citizens ofthe United' States, both residing at Oskaloosa, in the county of Mahaskaand State of Iowa, have invented certain new and useful Improvements inAutomatic Motor-Controllers, of which the following is a specification.

Our invention relates to means for automatically shutting off power ofstationary engines, and the invention is intended to be attached to astationary gas engine or like motor where there is no attendant incharge and no one to stop the engine when the work desired of it iscompleted.

Gasolene engines are very largely used for the purpose of pumping waterin mines and in farming operations. A gasolene engine, after it isstarted, needs no one in charge to look after it, but it does need anattendant to stop it after it has completed its work, otherwise it willcontinue to run, thereby wasting gasolene, electricity and oil, at arelatively heavy loss. In order to overcome this, operators of thisclass of engines, who have had no one to look after the engine, havefilled the gasolene tank and the lubricator only with what oil seemed tobe sufficient for the full operation of the engine to complete the workdesired, but not only is this to a great extent guesswork, but even didthe gasolene become exhausted, and the engine from lack of explosionshut down, the electric current and the lubricating oil would continueto flow until such time as they were shut off by hand, the batterybecame exhausted, or the oil supply ran out.

The object of our invention is to do away with this difliculty byproviding a device which may be set by the operator so that the enginemay run a predetermined time, and then the various operative parts ofthe engine may be shifted so as to shut off the lubricating oil, thegasolene and the flow of electricity, thereby saving a great deal oftrouble.

lVith our invention, when the predetermined time is up, the switch inthe electric circuit is broken, thereby stopping the engine, and thefuel supply and lubricant sup- I ply closed.

For a full understanding of the invention and the merits thereof, and toacquire a knowledge of the details of construction, reference is to behad to the following description and accompanying which:

Figure 1 is a side elevation of our device,

showing the switch closed and the shifting lever in its inoperativeposition; Fig. 2 is a like View, however, showing the switching leverinits operative position and the latch tripped; Fig. 3 is a transversesection on the line 3-3 of Fig. 1; Fig. 4 is a transverse section acrossthe lower end of the frame; Fig. 5 is a detail perspective View of thedog 47, and, Fig. 6 is a detail perspective view of the switch and aportion of the adjacent mechanism.

' Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to these figures, it will be seen that our device is supportedon a rectangular frame of iron bars 22 having the cross bars 3, 4 and 5.Bolted to the rear of this frame, and extending diagonally across thecross bar 4 are the braces 6. This frame is preferably bolted togetheror the members of it otherwise attached to each other in any desiredmanner.

Pivotally mounted on the. bar 3 is the ratchet disk 7 having ratchetteeth upon its circumference and provided with the outstanding pin 8'projecting from its face. Mounted on the bar 4 is the ratchet tootheddisk 9 overlapping the disk 7 and provided with ratchet teeth with whichthe pin 8 engages once in every revolution of the disk 7. This disk 9 isprovided with the outwardly projecting pin 10 and is also provided witha graduated scale 9 upon its face. Rot-atably mounted on the cross bar 5is the disk 11 also provided with teeth upon its periphery with whichthe pin 10 engages, and having upon its face the outwardly projectingpin 12. This disk 11 is also provided with the graduated scale 11 Thesedisks are rotatably mounted on stud bolts 13 projecting from thetransverse bars 3, 4 and 5, each stud bolt being surrounded by a spring14 which acts to hold the disk in place. WVe do not wish to limitourselves, however, to this mode of mounting the rotatable disks. Itwill be seen that one complete revolution of the disk 7 will cause amovement of the disk Qequal to the space between the teeth on disk 9,while a complete rotation of the disk 9 will cause the drawing, in

disk 11 to move one step, or the distance between the teeth 'on disk 11.As shown, the three disks 7, 9 and 11 are so geared to each other thatthirty revolutions of disk 7 will cause one revolution of disk 9, andthat nine hundred revolutions of disk 7 will cause one revolution ofdisk 11.

Attached to the upper end of one of the longitudinally extending framebars 2 are the opposed plates 15, one of which plates has the inwardlyextending prolongation 16 having a perforated head at its end throughwhich the stud bolt upon which the disk 7 is mounted, extends. Thisprolonged strip 16 is folded intermediate of its ends to form a bridge18 to accommodate the pin 8 and permit the disk to be rotated. Supportedoppositely to the center of the disk 11 is a plate 20 having anextension strip 21 formed with a perforated head 22 and the returnedbend 23 forming the bridge permitting the passage of the pin 12. Thisstrip is provided with a pointer 24 in registry with the graduated scale11*. Intermediate between the plates 15 and 20 is the plate 25 havingthe prolongation 26 through which the stud bolt passes. This strip 26 iscurved to form a bridge to permit the passage of the pin 10, and is alsoprovided with the pointer 28. Mounted on the plate 25 is the switch 30which is connected to a spark coil. A switch arm 31 is connected by aconnecting rod 32 to the setting lever 33 which is pivoted at its lowerend in a clip 34. Said setting lever is provided with a" pin 35 whichengages in the notches of a lever 36 pivoted to one of the longitudinalbars by a bolt 37. The pin 12 on the disk 11 is adapted to contact withthe inwardly projecting free end of the latch lever 36 so as todepressthe free end and raise the outer or notched end from engagementwith the pin 35. Pivotally mounted between the plates. 15 is the lever40 connected at its lower end to an angular member 41. To the angularmember is connected an adjusting bolt 42 having attached thereto thecoil spring 43 whose other end is connected to a hooked link 44 pivotedat 45 to the setting lever 33. A link 46 connects the latch 36 to thelink 44 so that the tension of the spring 43 is exerted upon the latchto hold it in engagement with the pin 35. The upper end of the lever 40carries upon it the pivoted U-shaped dog 47 whose U-shaped end overlapsthe margin of the disk 7 and engages with the teeth of said disk.Mounted upon the opposite longitudinal frame bar is the pivoted rod 48having pivotally attached thereto the inwardly projecting dog 49 whoseend is downwardly bent as at 49 to engage with the teeth on the disk 7and prevent a reverse motion of the disk. The angular member 41 isadapted to be connected to any suitable reciprocating part A of a gasengine or motor C, as for instance, a sparking lever and a cam B, sothat a reciprocating motion may be given to the lever 40 and astep-by-stcp motion communicated to the disk 7. Upon the lever 33 is aconnection 50 which leads to the throttle valve actuating mechanism ofthe engine and also to the valve of an oil cup or other lubricatingdevice. The switch 30 is connected in circuit with the spark coil sothat upon a retraction of the lever 33, the switch arm 31 will beshifted to break the circuit to the spark coil.

As illustrative of the application of our mechanism We have showndiagrammatically the cylinder of the motor C as provided with a sparkplug 51. A wire 52 leads to the secondary of an induction coil D andfrom thence to one terminal 31 of the switch. From the other terminal 31a wire 53 leads to a ground. The frontal valve of the engine C isdesignated 54 and is shown as connected by a chain 50 to the lever 33.

The operation of our invention is as follows: The disks 9 and 11 may beset to any desired number on their graduated scales. With the ordinaryspeed of an engine, it requires forty seconds to make one revolution ofdisk 7. Now supposing that the disks 9 and 11 are set so that the number2 on the graduated scale is opposite to the index pointer, it will beobvious that it will require sixty-two revolutions of the disk 7 tooperate the trip and stop the engine, and thus the device will betripped in about one hour. By setting the disks 9 and 11 so that thenumeral 30 on the graduated scale comes opposite to the index pointer,the mechanism will be set so that it will run eight hours and thenautomatically disconnect the engine. This is done by opening the switchin the ignition circuit. In order to prevent any waste of the liquidfuel or the lubricating fluid, the operating member 33 is alsoconnected, as described, to any suitable means for controlling the. flowof the fuel and lubricating fluid to the engine. It will be obvious toothat by operating the lever 36 by hand, the various parts will bedisconnected. Upon raising the lever 36, the spring 43 will act to drawthe lever 33 inward, as before described.

\Vhile we have shown what we believe to be the best and most effectiveform of our apparatus, we do not wish to be limited to this form, as itis obvious that various changes may be made in minor details and theform of arrangement of the parts, without departing from the spirit ofour mvention.
